Title: Process for the preparation of a mixed fertiliser containing easily assimilable phosphates and nitrogen
IPC: C05B1/06
Filed: 1931-11-27
Abstract: Fertilizers are prepared by treating solid mineral acid decomposition products of raw mineral phosphates with concentrated ammonia in countercurrent at above 75 DEG  C., the water evaporated by the reaction being prevented from condensing in the decomposition products or in the ammonia reaction products obtained therefrom which have absorbed less ammonia than 1-2 molecules of ammonia per molecule of phosphoric acid.  The water vapour produced by the reaction may be wholly or partially condensed in such reaction products as contain ammonia in the ratio of approximately 2 molecules of ammonia to 1 molecule of phosphoric acid.  The product may be completely saturated with ammonia.  The process may be carried out in a rotary drum having means for feeding in the solid decomposition products at one end and ammonia at the other, a cooling tube extends half-way along the drum from the end at which the solid products enter and underneath this is a gutter or channel in which the condensed water is collected and removed, e.g. into contact with such products as have absorbed approximately 2 molecules of ammonia per molecule of phosphoric acid. Alternatively the treatment with concentrated ammonia in countercurrent at above 75 DEG  C. may be carried out so that the main reaction with ammonia takes place as close as possible to the place of entry of the solid decomposition products into the apparatus, an excess of ammonia being used.ALSO:Fertilizers are prepared by treating solid mineral acid decomposition products of raw mineral phosphates with concentrated ammonia in counter current at above 75 DEG  C., the water evaporated by the reaction being prevented from condensing in the decomposition products or in the ammonia reaction products obtained therefrom which have absorbed less ammonia than 1-2 molecules of ammonia per molecule of phosphoric acid.

Title: Recovery of cobalamins
IPC: C07H23/00
Filed: 1960-09-26
Abstract: Cobalamin is separated from an addition product of cobalamin with a substituted aromatic hydroxy carboxylic acid, such acid being hydroxynaphthoic, methylene - bis - hydroxy - benzoic or methylene - bis - hydroxy - naphthoic acid or a nuclearly substituted lower alkyl, phenyl, halogeno or nitro hydroxybenzoic, hydroxy naphthoic, methylene - bis - hydroxy - benzoic or methylene-bis hydroxy naphthoic acid, by contacting an aqueous solution of the addition product at a pH of 4.7 to 7.0 with a carboxylic ion exchange resin which has been prepared by (1) treatment at a pH of more than 7 with an aqueous metal hydroxide solution followed by (2) adjustment of the pH of the resin to 4.7 to 7.0, whereby the cobalamin is selectively affixed to the resin.  The resin is used in granular or particulate form and may be obtained by copolymerising and/or cross-linking polyacrylic acid or polymethacrylic acid with divinyl aromatic compounds such as divinyl benzene, as described in U.S.A. Specifications 2,340,111 and 2,996,430.  The adjustment of the pH may be effected by the use of acids such as acetic acid, hydrochloric acid or sulphuric acid, and bases such as sodium hydroxide, potassium hydroxide, ammonium hydroxide, pyridine, tributylamine and picoline, and buffers based on the phosphate, acetate, citrate or phthalate systems.  The cobalamin is recovered from the resin by eluting with an aqueous sodium hydroxide solution and then the solution brought to a pH of 4-6 with concentrated sulphuric acid and the resultant solution recovered by evaporation in vacuo, freezing and drying, recrystallisation, or by absorption on charcoal, alumina or silica gel.  The solution may also be treated with a cyanide such as sodium, potassium, barium, calcium, or strontium cyanide or an alkali metal ferrocyanide or ferricyanide to increase the yield.  Acetone, methyl ethyl ketone or chloroform may be used to wash the resin with the cobalamin affixed.

Patent GB-887992-A (GB)
Title: A system for maintaining in an enclosure an atmosphere conditioned for physiological needs
IPC: A62B7/14
Filed: 1959-09-29
Abstract: 887,992. Respiratory apparatus. BENDIX CORPORATION. Sept. 29, 1959 [Oct. 6, 1958], No. 33065/59. Class 81 (2). [Also in Group XIII] In a respiratory apparatus, low-temperature respiratory fluid is supplied to a Venturi pump alternately, under the control of valves, through each of a pair of heat-exchangers past both of which gas from an enclosed respiration space is circulated, the gas being entrained by the pump and recirculated with the respiratory fluid to the enclosed space. The respiratory fluid is supplied from a double-walled liquid-gas converter vessel 32 having a filling line 34 controlled by a valve 35. Liquid respiratory fluid which trickles into a line 36 is evaporated in a coil 37 and passes through a pressure-closing valve 38 and a valve 39, which is opened to atmosphere only when the vessel 32 is being filled, to the space above the liquid in the vessel to create a pressure sufficient to force the liquid through a line 30 to the heat-exchangers 20, 21 which are disposed in a housing 13. Used gas from the enclosure 10 is circulated in the housing around the heat-exchangers where it is cooled, the respiratory fluid thus being evaporated. Evaporated respiratory fluid then passes under the control of a three-way valve 15 alternately from each of the heat-exchangers to the Venturi pump nozzle 26 by way of a valve 16 which is controlled in accordance with the temperature of gas in the enclosure. The circulating gas is drawn into the aspirating inlet of the Venturi pump and is discharged with the respiratory fluid into the enclosure. The three-way valve alternately connects the heat-exchangers to the Venturi pump sufficiently frequently to prevent the heat-exchanger efficiency being unduly impaired by the formation of frost from perspiration in the gas from the enclosure. Melted frost and condensate collects in a trap 40. To remove excess carbon dioxide from the system some gas is discharged from the enclosure through a check-valve 25. The enclosure may be provided in a suit comprising an outer impermeable layer 50 and an inner permeable layer 51 and having a window 52 above which are gas outlets 53. A housing 55 at the back of the suit contains the heat-exchangers and the pump and supports the liquid-gas converter. Gas flows from the pump to the space between the suit layers, where it is used for respiration, cooling the body and collecting perspiration and after use is conducted back to the housing 55 by a pair of ducts 81 extending from inside the inner suit layer and over the wearer's shoulders.
